In the triangle below, what ratio is sec h?

We know that
in the right triangle FGH
cos H=adjacent side angle H/hypotenuse
adjacent side angle H=g
hypotenuse=f
so
cos H=g/f
sec H=1/cos H
sec H=1/(g/f)> sec H=f/g

the answer is
sec H=f/g

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
